Activated Partial Thromboplastin Time (APTT) Test

APTT Test: A Comprehensive Analysis of Blood Clotting and Coagulation

The APTT (Activated Partial Thromboplastin Time) test is a crucial diagnostic tool for assessing a patient’s blood clotting time and detecting various coagulation disorders. This test is used to measure the time it takes for blood to clot and is essential for diagnosing and managing bleeding disorders, as well as detecting the effectiveness of blood-thinning medications.

Test Details

• Turnaround Time: The APTT test typically takes 1 to 3 business days to provide results.
• Sample Type: This test requires a blood sample taken while the patient is fasting, meaning no food or liquids other than water should be consumed after midnight before the test.
• Price: The cost of the APTT test varies depending on the location and provider, with prices often ranging from $150 to $250.

 Uses of Activated Partial Thromboplastin Time

The APTT test is used for various purposes, including:

1. Diagnosing and grading bleeding disorders: APTT testing is used to diagnose and grade bleeding disorders and detect the effectiveness of treatments.
2. Monitoring blood-thinning medication: The test is used to monitor the effects of blood-thinning medications, such as warfarin, in patients with conditions like atrial fibrillation or a history of blood clots.
3. Evaluating risk for blood clots: APTT testing can help evaluate the risk of blood clots in patients undergoing surgery or with certain medical conditions.

Preparation

To prepare for the APTT test, please follow these guidelines:

• Avoid food and liquids other than water after midnight before the test.
• Take prescription medications as directed by your doctor.
• Inform your doctor if you have any known medical conditions or are taking any medications, as some drugs can affect the test results.

Results

APTT test results are interpreted by comparing them to a reference range for a healthy population. The test is considered reproducible, specific, and sensitive. If the test results are abnormal, your doctor may recommend further testing or treatment to address any underlying conditions or medication adjustments.
